If you’re a macOS power user, it’s likely that you’ve already searched for a solution to prevent your computer from going to sleep mode for an extended period of time. This is quite handy when launching a tool that takes a bit of time and you need to step away.
The tools Caffeine and Amphetamine were previously the most popular solutions for this kind of need. However, Caffeine has not been updated for a long time, while Amphetamine has not been updated since 2021. Fortunately, there is an open-source and up-to-date alternative called KeepingYouAwake.
This small application resides in the macOS menu bar (version 10.13 and newer) and allows you to prevent your Mac from going into sleep mode for a duration of your choice or as long as you keep it active. The application is very easy to use and has several interesting features such as predefined activation durations, the ability to automatically turn off when the battery level is low, as well as support for Retina display and dark mode.
In addition, the application is available in several languages. To function, KeepingYouAwake uses a well-known command called “caffeinate”, which is integrated into all current macOS systems. However, it is important to note that on a MacBook, the application will only work when the screen is open.
The application is distributed under the MIT license, which means that it is free and open-source, and if you are a developer, you are free to improve it or add new features.
In short, it’s super handy for preventing your Mac from falling asleep while you go and rest.
